Technical Field

The present application relates to the field of communications, and more particularly, to a method for optical power regulation, a regulation and measurement system, a control device, and a regulation and measurement site.

Background

In an optical communication network, when service performance is degraded, wavelength service needs to be power-adjusted and tested. For example, service performance is degraded due to fiber splicing, fiber degradation, station insertion loss degradation, manual mishandling, etc., and wavelength services require power tuning.

An existing debugging and testing method is based on an Optical Multiplex Section (OMS) serial stepping debugging and testing, that is, manual selection of debugging and testing services and distributed serial power debugging and testing. Specifically, the service to be measured and the affected service are traversed from the service source to the destination based on OMS and serial small-step measurement. In order to ensure the safety of old wave service, the single OMS firstly regulates and measures the main optical path combined wave and then regulates and measures the single wave based on the debugging and measuring of the small step length trial-and-error performance of the current network power value. In addition, in order to reduce the influence on the old wave, the optical power of the old wave service is locked through small-step trial and error debugging. If the optical power lock fails, a single step rollback is performed. The commissioning process also monitors whether the bit error probability (BER) of the traffic is out of limit.

In the existing debugging mode, a service to be debugged needs to be manually selected, and based on the service path, the debugging is performed according to an OMS serial feedback mode, specifically, a debugging mode, a small step length debugging mode and a mode of repeatedly monitoring whether the BER of the service is out of limit are frequently interacted with equipment, a debugging scene is limited, and the debugging efficiency is low.

In a first aspect, a method of optical power regulation is provided. The method may be executed by the debugging system, or may be executed by a chip or a circuit configured in the debugging system, which is not limited in this application.

This debugging system includes: the method comprises the following steps of controlling equipment and N debugging and testing stations: the control equipment determines M services to be modulated and measured which need to be modulated and measured by optical power, wherein M is an integer greater than 1 or equal to 1; based on the M services to be tested, the control device sends testing information to the N testing stations, wherein the testing information is used for parallel optical power testing of the N testing stations, the N testing stations belong to the stations where the M services to be tested are located, and N is an integer greater than or equal to 1; and the N debugging stations carry out optical power debugging based on the debugging information.

Illustratively, the M services to be scheduled correspond to X optical multiplexing sections OMS, where X is an integer greater than 1 or equal to 1.

Illustratively, at least one of M, N, X is an integer greater than 1. Such as N greater than 1. For example, the control device may determine a traffic to be scheduled that passes through a plurality of scheduling sites. For another example, the control device may determine a plurality of services to be scheduled, which pass through a plurality of scheduling sites.

For example, the control device may further perform tuning and measurement by identifying the main optical path, specifically, the control device identifies that the optical performance data of the M main optical paths are abnormal, and based on the abnormal data, the control device sends tuning and measurement information to the N tuning and measurement stations, where the tuning and measurement information is used for parallel optical power tuning and measurement of the N tuning and measurement stations, where the N tuning and measurement stations belong to stations where the M main optical paths are located, and M, N are integers greater than 1 or equal to 1; and the N debugging stations carry out optical power debugging based on the debugging information.

Based on the technical scheme, parallel debugging and testing can be realized. The control equipment can firstly identify the service or the main light path which needs to be optimized and tested, then optimize the service or the main light path which needs to be optimized and tested, and send the testing information to each testing station, so that each testing station can perform parallel testing according to the testing information. The control device may centrally control: the system has the advantages that multiple services, multiple faults (namely, multiple services need to be optimized, adjusted and tested) and multiple adjusting and testing stations can realize automatic parallel optimization, adjustment and testing of multiple services, multiple OMS sections and multiple adjusting and testing stations, supports multiple services, multiple light paths and multiple fault scenes, and is suitable for more adjusting and testing scenes. In addition, debugging and testing can be optimized rapidly, and debugging and testing stations are tested in parallel as many as possible, so that the optimization debugging and testing efficiency is improved, and the requirements of customers for rapid automatic optimization debugging and testing are met as much as possible. It should be noted that, the present application is introduced based on a scenario in which parallel optical power modulation is performed according to a service to be modulated, but this should not limit the application scope of the present application, for example, the present application may also be applied to a scenario in which a control device performs parallel modulation according to an abnormality of a main optical path.

With reference to the first aspect, in certain implementations of the first aspect, the method further includes: the control equipment receives service optical performance data reported by W stations, wherein W is an integer greater than 1 or equal to 1; the control equipment determines M services to be modulated and measured which need optical power modulation and measurement, and the method comprises the following steps: and the control equipment determines the M services to be regulated and tested according to the service optical performance data reported by the W sites.

For example, W may be equal to N, or W may be greater than N.

For example, the W stations may include N testing stations, that is, the N testing stations may actively report the service optical performance data. Or, the W sites may include partial debugging sites, and after the control device determines M services to be debugged, the control device determines N debugging sites through which the M services to be debugged pass.

Illustratively, the light performance data may include, for example, but is not limited to: the optical amplifier comprises an optical amplifier single board input/output composite wave optical power, a single wave optical power, an optical amplifier gain, an Electronic Variable Optical Attenuator (EVOA) attenuation value, and a Bit Error Rate (BER).

Based on the technical scheme, the control equipment can monitor the optical performance data of the whole network service in real time, analyze the monitored optical performance data of the service and determine the service needing to be optimized and debugged. Therefore, automatic and rapid optimization debugging and measurement can be realized, manual intervention is avoided, and operation and maintenance are simplified.

With reference to the first aspect, in certain implementation manners of the first aspect, the sending, by the control device, the commissioning information to the N commissioning stations includes: the control equipment sends T times of debugging information to the N debugging stations, so that the N debugging stations can conduct parallel optical power debugging based on the received debugging information each time, and T is an integer equal to or greater than 1; the method further comprises the following steps: after each optical power regulation of the N regulation and test sites, feeding back a regulation and test response to the control equipment, and inquiring real-time optical power information of the M businesses to be regulated and the affected businesses by the control equipment based on the regulation and test response; or after T1 th optical power modulation of the N modulation sites, feeding back a modulation response to the control device, where the control device queries real-time optical power information of the M services to be modulated and affected services based on the modulation response, and T1 is an integer greater than 1 and less than or equal to T; or after the accumulated adjustment quantity of any one of the N modulation and measurement sites reaches a first threshold value, feeding back a modulation and measurement response to the control device, and the control device querying real-time optical power information of the M services to be modulated and the affected services based on the modulation and measurement response; or after the total accumulated adjustment amount in the N adjustment and measurement sites reaches a second threshold value, feeding back an adjustment and measurement response to the control device, and the control device querying real-time optical power information of the M services to be adjusted and the affected services based on the adjustment and measurement response.

As an example, after each commissioning, the control device may query the commissioning traffic and the affected traffic for relevant optical power information. This scheme can be used when T is greater than 1 or equal to 1. When T is equal to 1, after the debugging and testing of the debugging and testing station is finished, the control equipment inquires the relevant optical power information of the debugging and testing service and the affected service; when T is larger than 1, the method indicates that the modulation is performed for multiple times, and after each modulation and measurement of the modulation and measurement site is completed, the control equipment inquires the related optical power information of the modulation and measurement service and the affected service. By the scheme, the debugging result can be monitored in real time, so that the overall debugging efficiency can be improved, and unnecessary debugging and time cost and calculation cost brought by unnecessary debugging are reduced.

As another example, if a certain condition is satisfied (e.g., based on the number of times of commissioning or the amount of commissioning), the control device queries the commissioning service and the related optical power information of the affected service. This scheme may be used, for example, when T is greater than 1. In this example, in each adjustment, a small step size adjustment and measurement can be used, so that the excessive adjustment amount of a single adjustment and measurement can be avoided, and the adjustment and measurement safety can be improved. In addition, the time cost and the calculation cost caused by frequent inquiry of real-time optical power by the control device can be reduced. Especially, in a scene that the network topology is large and the span of the service to be measured and the affected service passing through the network element is large, the automatic parallel optimization measurement mode that the small step length of each station is used for multiple times of measurement is considered, a certain condition (such as after a certain measurement is accumulated) is met for feedback, and the time consumed by multiple real-time optical power query of the control equipment is reduced.

In a second aspect, a method of optical power regulation is provided. The method may be executed by the control device, or may be executed by a chip or a circuit configured in the control device, which is not limited in this application.

The method can comprise the following steps: the method comprises the steps that the control equipment determines M services to be regulated and tested, wherein the M services need to be regulated and tested by optical power, and is an integer larger than 1 or equal to 1; based on the M services to be tested, the control equipment sends testing information to N testing stations, and the testing information is used for parallel optical power testing of the N testing stations; and the N debugging sites belong to sites where the M services to be debugged are located, and N is an integer greater than 1 or equal to 1.

Based on the technical scheme, parallel debugging and testing can be realized. The control equipment can firstly identify the service needing to be optimized and tested, then optimize the service needing to be optimized and tested and send the testing information to each testing station, so that each testing station can conduct parallel testing according to the testing information. The control device may centrally control: the system has the advantages that multiple services, multiple faults (namely, multiple services need to be optimized, debugged and tested) and multiple debugging and testing stations can realize automatic parallel optimization, debugging and testing of multiple services, multiple OMS sections and multiple debugging and testing stations, supports multiple service and multiple fault scenes, and is suitable for more debugging and testing scenes. In addition, debugging and testing can be optimized rapidly, and debugging and testing stations are tested in parallel as many as possible, so that the optimization debugging and testing efficiency is improved, and the requirements of customers for rapid automatic optimization debugging and testing are met as much as possible.

With reference to the second aspect, in certain implementations of the second aspect, the method further includes: the control equipment receives service optical performance data reported by W stations, wherein W is an integer greater than 1 or equal to 1; the control equipment determines M services to be modulated and measured which need optical power modulation and measurement, and the method comprises the following steps: and the control equipment determines the M services to be regulated and tested according to the service optical performance data reported by the W sites.

With reference to the second aspect, in some implementations of the second aspect, the sending, by the control device, the commissioning information to the N commissioning stations includes: the control equipment sends T times of debugging information to the N debugging stations, so that the N debugging stations can conduct parallel optical power debugging based on the received debugging information each time, and T is an integer equal to or greater than 1; the method further comprises the following steps: after each optical power regulation of the N regulation and test sites, receiving regulation and test responses fed back by each regulation and test site, and inquiring real-time optical power information of the M businesses to be regulated and the affected businesses; or after T1 th optical power modulation of the N modulation sites, receiving a modulation response fed back by each modulation site, and querying real-time optical power information of the M services to be modulated and affected services, where T1 is an integer greater than 1 and less than or equal to T; or after the accumulated regulating quantity of any one of the N regulating and testing stations reaches a first threshold value, receiving regulating and testing responses fed back by each regulating and testing station, and inquiring the real-time optical power information of the M services to be regulated and the affected services; or after the cumulative total adjustment amount of the N adjustment and measurement stations reaches a second threshold value, receiving adjustment and measurement responses fed back by each adjustment and measurement station, and inquiring the real-time optical power information of the M services to be adjusted and measured and the affected services.

With reference to the first aspect or the second aspect, in some implementation manners, the M services to be tested correspond to X optical multiplexing sections OMS, where X is an integer greater than or equal to 1, and before the control device sends the testing information to the N testing stations, the method further includes: the control device calculates at least one of the following for each of the X OMSs: the total absolute adjustment amount of the combined wave, the total absolute adjustment amount of the single wave and the relative adjustment amount of each adjusting and measuring station.

Illustratively, the total absolute adjustment amount of the combined wave is: difference between optical amplification gain and composite attenuation.

Illustratively, the absolute adjusted total amount of the single wave: subtracting the value of the actual optical power of the single wave from the target optical power of the single wave.

Illustratively, the relative adjustment amount of each tuning and testing station is as follows: and subtracting the accumulated adjustment quantity of the upstream debugging station positioned at the debugging station from the absolute adjustment total quantity of the debugging station.

Based on the technical scheme, the multi-service parallel debugging is considered, so the control equipment can calculate the total adjustment amount of the OMS section, and further can determine the adjustment amount of each debugging station. In addition, considering that the optical power changes after the optical power at the upstream of the service is adjusted, the optical power at the downstream of the service also changes correspondingly, so that through the hedging of the upstream and downstream adjustment quantities, the adjustment quantity at the downstream site can be obtained by subtracting the adjustment quantity accumulated by all the OMS from the adjustment quantity of the optical power of each wave at the downstream site, and a separate truncation operation is not needed.

With reference to the first aspect or the second aspect, in some implementations, before the controlling device sends the commissioning information to the N commissioning stations, the method further includes: the control equipment respectively calculates at least one item of the following information of each debugging station in the N debugging stations: the optical power adjustment amount of the combined wave and the optical power adjustment amount of the single wave.

Based on the technical scheme, the main optical path and the single-wave step length are independently calculated and decoupled with each other, so that the repeated calculation of the combined-wave power regulating quantity can be avoided, the debugging times are reduced, and the debugging efficiency is further improved.

With reference to the first aspect or the second aspect, in some implementations, the optical power adjustment amount of the combined wave, and/or the optical power adjustment amount of the single wave, satisfies at least one of the following: the optical power adjustment quantity of the service to be measured on the same debugging site, which passes through the same OMS section, in the M services to be debugged is smaller than or equal to a third threshold value after being counteracted in the forward and reverse directions; the adjustment quantity of the optical power in the same direction on the N1 debugging and testing stations is less than or equal to a fourth threshold value, wherein the N1 debugging and testing stations belong to the debugging and testing station where the same service to be debugged is located, the N1 debugging and testing stations belong to the N debugging and testing stations, and N1 is an integer greater than 1 or equal to 1.

Based on the technical scheme, the limitation of the parallel debugging and measuring step length in the same direction can be considered. Specifically, it is considered that if each OMS section is issued in parallel according to the minimum step length, the influence on other affected waves is small, the safety is high, and the debugging efficiency is improved a little; if the maximum step length of each OMS section is sent down in parallel, service interruption may be caused if the debugging values of all debugging stations are not effective simultaneously and only effective in the same direction. Therefore, the limitation of the parallel-modulation co-modulation step size can be considered. In the embodiment of the application, the safety influence of the debugging and the testing on other waves and the requirements of the debugging and the testing performance are considered, and the single station (OMS) step length constraint and the inter-station (OCH level) equidirectional debugging and testing step length constraint are considered and issued in parallel according to the OMS section, so that the influence on other waves is controllable, and the parallel debugging and testing performance is high.

With reference to the first aspect or the second aspect, in certain implementations, the method further includes: and the control equipment calculates the optical power adjustment quantity of the influenced service according to the degradation quantity of the influenced service before and after the debugging and the testing of the N debugging and testing stations, wherein the influenced service represents the service influenced by the debugging and the testing of the N debugging and testing stations.

Illustratively, the amount of optical power adjustment for the affected traffic is based on: and determining a first value and a second value, wherein the first value represents the optical signal to noise ratio attenuation value of the affected service before the N modulation and detection sites modulate and detect, and the second value represents the optical signal to noise ratio attenuation value of the affected service after the N modulation and detection sites modulate and detect.

Based on the technical scheme, in the debugging process, the influence of the debugging process on the old waves can be evaluated, especially in the scene that fault exists in the main light path debugging and the single waves, and the influence of the main light path on the single wave service state can be debugged, so that the problem of service interruption can be avoided, and the debugging safety can be improved. Specifically, for example, to ensure that the performance of the affected old wave does not deteriorate (e.g., OSNR deterioration), the amount of pre-adjustment of the old wave optical power may be calculated by comparing the amount of deterioration of the old wave before and after the adjustment.

With reference to the first aspect or the second aspect, in certain implementations, the commissioning information includes at least one of: the system comprises an optical amplifier gain, an optical amplifier gain adjustment quantity, information of a debugging and testing station, an attenuation value of an electronic variable optical attenuator, an optical attenuation adjustment quantity, a debugging and testing wave channel number, a debugging and testing wave optical power adjustment quantity, an affected wave channel number and an affected wave optical power adjustment quantity.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various optical communication systems or optical networks, or can be applied to any communication system needing optimized debugging and testing.

For the understanding of the embodiments of the present application, a communication system suitable for the embodiments of the present application will be described in detail with reference to fig. 1 and 2.

Fig. 1 is a schematic diagram of a system architecture suitable for the method provided by the embodiment of the present application. It should be understood that the system architecture shown in fig. 1 is merely exemplary for ease of understanding, and should not limit the scope of the application.

As shown in fig. 1, the system includes a communication network 110 and a network management system 120. The communication network 110 may include at least one network device 111 to 118, and each network device may run an optical layer service thereon. A network device may be understood as an object in a communication network that needs to be managed. The network device may be implemented by software, for example, a virtual machine, a container, an application, etc.; hardware implementations such as servers, base stations, switches, routers, relays, mobile terminals, personal computers, diskettes, solid state drives, and the like can also be employed; and the method can also be realized by adopting a combination of hardware and software. The present application is not limited to the specific form of the network device. Illustratively, the network device may be a distributed network element, and the network management system 120 may be a centralized control unit.

The network management system 120 may include an information acquisition device 121 and an information processing device 122. The information collecting device 121 may be used to collect and manage information, such as optical performance data, of each network device in the communication network 110. For example, the information collecting device 121 may be communicatively connected to the communication network 110, and any one of the network devices in the communication network may transmit the optical performance data to the information collecting device 121. The information collecting device 121 may provide the received information to a subsequent information processing device 122 for processing based on the information, such as whether optical power adjustment is required based on information analysis.

It should be understood that the above is merely for ease of understanding, and the network management system 120 is partitioned based on different functions. This should not be construed as limiting the application in any way.

In one design, the network management system 120 may be deployed on a physical device, for example. The physical device may include one or more processors and one or more memories. The memory may store instructions, and when the instructions are loaded and executed by the processor, the functions executed by the network management system 120 may be implemented. For example, the functions of each device and each module listed above may be implemented by a processor executing the corresponding instructions. Of course, the physical device may also include an input-output interface, such as a wired or wireless network interface, to communicate with the outside world. The physical device may also include components that may be used to implement other functions. For brevity, no further description is provided herein.

In another design, the network management system 120 may be distributed over multiple physical devices. The plurality of physical devices may form a device cluster. The cluster of devices may include one or more processors and one or more memories. The memory may store instructions, and when the instructions are loaded and executed by the processor, the functions executed by the network management system 120 may be implemented.

In addition, each physical device may further include an input-output interface for communication between the physical devices and communication with the outside. The device cluster may also include components that may be used to implement other functions. For brevity, no further description is provided herein.

Fig. 2 is another schematic diagram of a system architecture suitable for the method provided by the embodiment of the present application. It should be understood that the system architecture shown in fig. 2 is merely exemplary for ease of understanding, and should not limit the scope of the application.

As shown in fig. 2, the system includes one or more nodes (or stations or network elements), such as node 211, node 212, and node 213 in fig. 2, which can communicate with each other. One or more network management devices, such as network management device 220 in fig. 2, may also be included in the system. Illustratively, the network management device may be, for example, a centralized control unit or an Automatic Control Center (ACC) or the like.

The network management device may include a first device and a second device, and the node may include the second device and a third device.

Exemplarily, the first device may be denoted as a NETWORK (NETWORK) Optical Data (OD) device, for example. The second device may be recorded as a path computing element communication protocol (PCEP) control device, for example. The third device may be denoted as a Network Element (NE) OD (NE _ OD) device, for example.

Illustratively, the first device may be, for example, the brain, providing control of the entire parallel commissioning process. The first device may for example comprise four modules: the system comprises an optical sensor (sensor) module, a debugging data management module, a debugging algorithm module and a debugging control module.

Light sensor module: the module can collect and monitor optical performance parameters of an OMS (optical channel, OCH) and upload the optical performance parameters to a debugging data management module. Optical performance parameters may include, for example, but are not limited to: optical power, bit error rate, bit error probability (BER), etc.

A debugging data management module: the module can realize data splicing (such as according to network topological relation), data life cycle management (real-time data or historical data), data cleaning or preprocessing and the like.

The tuning algorithm module: the module can calculate some debugging information by modeling the optical property physical parameters, such as: the target optical power of the service to be regulated and tested, the optimal regulating step length of the service to be regulated and tested, the regulating quantity of each old wave of the affected service and the like are provided for the regulating and optimizing control module to carry out parallel regulation and testing.

The tuning control module: the module can automatically identify the batch performance degradation service, the multi-service multi-fault parallel debugging and testing of each network element and the multi-round debugging and testing control and the like.

Illustratively, the second means may be for, for example: real-time resource reporting of network optical performance, adjustment amount issuing control and the like. The second device can ensure that real-time optical performance resources are automatically sent to the NETWORK _ OD device.

Illustratively, the third means may be for example: network element debugging performance data management and network element debugging control. Network element debugging performance data management: millisecond-level collection of optical performance data of a single board of the equipment and management of optical performance data of optical devices on network element services. Network element debugging and controlling: and the network element calls the execution and response of the testing action. The third device can collect millisecond-level optical performance data in real time and provide network real-time data for an automatic system.

In this embodiment, the control device may correspond to the network management device 220. The network management device 220 may be deployed on an independent server, or may be deployed on a network element device (i.e., a node), which is not limited to this. For example, the first apparatus may be deployed on a stand-alone server or on a network element device with greater capabilities.

In the embodiment of the present application, the debugging station may correspond to each node (or each network element) (e.g., node 211 to node 213).

It should be understood that the above is only for ease of understanding, and the network element, the network management equipment 220, and the first device are divided based on different functions. This should not be construed as limiting the application in any way. It will be appreciated that the functionality implemented by the various devices remains the same, although the division may be different.

Take network management equipment as an example. In one design, the network management device 220 may be deployed on a physical device, for example. The physical device may include one or more processors and one or more memories. The memory may store instructions, and when the instructions are loaded and executed by the processor, the functions executed by the network management device 220 may be implemented. For example, the functions of each device and each module listed above may be implemented by a processor executing the corresponding instructions. Of course, the physical device may also include an input-output interface, such as a wired or wireless network interface, to communicate with the outside world. The physical device may also include components that may be used to implement other functions. For brevity, no further description is provided herein.

In another design, the network management device 220 may be distributed and deployed on multiple physical devices. The plurality of physical devices may form a device cluster. The cluster of devices may include one or more processors and one or more memories. The memory may store instructions, and when the instructions are loaded and executed by the processor, the functions executed by the network management device 220 may be implemented.

For example, the first and second apparatuses listed above may be deployed independently on two physical devices. The functions of each device may be performed by the processor in each physical device executing the corresponding instructions. The functions of the modules in the first device can be further realized by the processor executing corresponding instructions. Alternatively, the functions of the modules in the first apparatus may be implemented by independent multiple physical devices, and each module is deployed on one physical device. This is not a limitation of the present application. In addition, the present application does not limit the division of each module in the first device.

It should be understood that the above-mentioned names are only used for distinguishing different functions, and do not represent that the first device and the second device are separate physical devices or that the second device and the third device are separate physical devices, and the present application is not limited to the specific form of the first device, the second device and the third device, and for example, they may be integrated into the same physical device or may be different physical devices. Furthermore, the above nomenclature is only used to distinguish between different functions, and should not be construed as limiting the application in any way, and this application does not exclude the possibility of other nomenclature being used in 5G networks and other networks in the future.

It should also be understood that the system architectures illustrated in fig. 1 and 2 are merely examples for ease of understanding and should not limit the scope of the present application. For example, the present application may be applied in any scenario where optical communication is performed.

To facilitate understanding of the embodiments of the present application, a brief description of several terms referred to in the present application will be given below.

1. Optimizing and testing: in some scenarios, such as natural aging of optical fibers, abnormal single boards, or artificial failures, the combined optical power may deviate from the reference value in a large range after long-term operation, which results in general deviation of the optical power of each single wave and deterioration of the optical power performance. The optical power is adjusted to a nominal value by adjusting the optical amplifier gain and the attenuation value of the adjustable optical attenuation in the network, so as to ensure the normal and stable operation of the system.

2. Old wave: the existing channels on the rerouted or expanded optical path are already present relative to the new add wave. The new wave will have an influence on the old wave performance.

3. Old wave allowance: an index capable of evaluating the capability of old waves for resisting disturbance caused by factors such as power, nonlinearity and the like. The higher the margin, the stronger the disturbance rejection.

4. Light crossing: optical cross-connect (OXC) is an optical fiber interface with multiple standards for controllably connecting and reconnecting any optical fiber signal (or its respective wavelength signal) to signals of other optical fibers at nodes of an optical network.

5. Optical Transmission Unit (OTU): a device or subsystem that can convert an incoming client-side signal to a Wavelength Division Multiplexing (WDM) standard wavelength output that conforms to standards (e.g., ITU-T G.694.1/ITU-T G.694.2) recommendations.

6. Wavelength Selective Switches (WSS): the reconfigurable optical add-drop multiplexer (ROADM) can realize a new generation technology of the dynamic reconfigurable optical add-drop multiplexer (ROADM), has a mesh structure, can support the function of any port wavelength ascending and descending, and has the function of adjusting the power of any wavelength light.

7. Optical Signal Noise Ratio (OSNR): an index that can evaluate the quality of an optical signal. The larger the OSNR, the better the optical signal quality, whereas the smaller the OSNR, the worse the optical signal quality.

8. Label Switching Path (LSP): a path which is divided according to special Forward Error Correction (FEC) and is formed by an input node (e.g. denoted as Ingress), an output node (e.g. denoted as iengs), and one or more Label Switching Routers (LSRs), and is used for packet transmission, which is established at a certain label stack level. The LSR has a processing device with a multi-Protocol label switching (MPLS) node function, and has a capability of forwarding an Internet Protocol (IP) packet of a pure layer 3 (L3). Ingress (MPLS input node) MPLS edge node to process IP packet traffic input to the MPLS domain. An ingress (MPLS output node) MPLS edge node, configured to process an IP packet flow output by an MPLS domain.

Optical layer services start from an OTU and pass through a plurality of optical devices such as an optical amplifier (which may be referred to as an optical amplifier for short), an optical fiber, a WSS, a comb filter Unit (ITL), a Fiber Interface Unit (FIU), an Electronic Variable Optical Attenuator (EVOA), etc., where light propagates in the form of an analog signal. The hole burning effect of the optical amplifier, the Raman effect of the optical fiber and the filtering effect of the WSS/ITL enable the optical signals of different channels to interact, and finally the change of the optical power and the OSNR is reflected.

One of the features that optimizes the tuning measurements includes: optical power of an optical layer network changes nonlinearly, multi-dimensional networking (wireless grid network (Mesh) networking) causes inter-dimensional influence, single-dimensional optimization may cause other dimensional faults, and the optical layer network and old waves transmitted in the same optical fiber are influenced by the adjusted and measured waves when the optical layer network and the old waves are adjusted and measured on a certain optical path. The old waves are affected differently by the difference of the positions, the quantity and the adjusting and measuring power of the adjusting and measuring waves. The same modulation and measurement wave positions and quantity and different modulation and measurement power have different influences on different wavelengths of old waves. In addition, the longer the same optical path of the modulation wave and the old wave is, the greater the influence on the old wave is. Therefore, there is a complex influence relationship among the factors such as the position, number, modulation power, affected old wave position, number, and path configuration parameters (span number, span length, device type, etc.). The channel modulation and measurement may cause interruption of the current network service, the MESH networking modulation and measurement sequence is difficult to judge, the modulation and measurement risk is large, and the required skill is high.

At present, in order to guarantee the network performance goodness, there are two main ways to debug: manual testing and tool testing.

The manual debugging and testing needs to control the debugging and testing position and step length and debug the affected business in the optimization debugging and testing process, the requirement on the skills of operation and maintenance personnel is very high, and the mode is time-consuming and labor-consuming.

And (3) tool debugging, namely, sequentially debugging and testing Optical Multiplex Section (OMS) layers one by one in a serial small step length mode, and when part of power is debugged and tested by the waves to be debugged, performing power locking on the affected old waves and monitoring whether the service is interrupted or not. The OMS serial debugging and testing, repeated debugging and testing of trial and error properties are time-consuming, the average debugging and testing performance is 30 minutes/wave, the debugging and testing safety is poor, no effective means is provided for ensuring the safety of self-service and other related services, and the scheme has limitation and cannot be used particularly in a multi-service multi-fault scene in a Mesh network.

The existing adjusting and testing method is as follows: based on the serial step-by-step debugging of the service OMS segment, that is, manually selecting the debugging service and the distributed serial power debugging, as shown in fig. 3. And traversing the service to be tested and the influenced service from the service source to the destination based on the OMS section serial small-step testing. In order to ensure the safety of old wave service, the single OMS section firstly adjusts the main light path combined wave of the wave to be adjusted and measured and then adjusts and measures the single wave based on the small step size of 0.5db debugging and measuring of the current network power value. And after the single OMS adjusts the accumulated 2db to take effect, carrying out power locking on the affected old waves in order to reduce the influence on the old waves. Specifically, the power of the old wave is guaranteed to be unchanged, that is, the power of the old wave is changed after the modulation and measurement wave is modulated and measured at the node, and the power of the old wave at the node is correspondingly adjusted by the node, so that the power of the old wave at the node is unchanged. And locking the optical power of the old wave service through small step length of 0.5db trial and error debugging. If the optical power locking fails, single step rollback is carried out, namely the influence on the service after the debugging cannot be predicted in advance, the upstream OMS section can be debugged and tested in one step only by 0.5dB step length, the rollback is immediately carried out after the service interruption occurs, the next OMS section is tried to be debugged, and the debugging or the rollback is continued according to an observation result. During the debugging process, whether the service BER is out of limit or not is monitored.

The existing debugging mode needs to manually select the service to be debugged, based on the service path, the debugging is carried out according to an OMS serial feedback mode, the debugging is wrong, the debugging with small step length and the monitoring of a receiving end are repeatedly executed, the debugging and the testing are frequently interacted with equipment, and the debugging and the testing efficiency are low. In addition, in the existing debugging and testing mode, the influence on old waves after debugging and testing cannot be evaluated, especially in the scene that fault exists in the main light path debugging and testing and single wave, the influence of the main light path on the single wave service state is not considered, so that service interruption is caused, and debugging and testing safety cannot be guaranteed.

In view of this, the present application provides a method, which can support a multi-service multi-fault scenario, centrally control a multi-service multi-fault multi-debugging station, and improve debugging efficiency and debugging safety.

Various embodiments provided herein will be described in detail below with reference to the accompanying drawings.

Fig. 4 is a schematic interaction diagram of a method 400 for optical power adjustment provided by an embodiment of the present application. The method 400 may include the following steps.

And 410, the control equipment determines M services to be modulated which need optical power modulation, wherein M is an integer greater than 1 or equal to 1.

The control device may identify a wavelength service that needs to be subjected to optical power modulation, or the control device may identify a wavelength service that needs to be subjected to optimal modulation, or the control device may identify a wavelength service that needs to be subjected to optical layer modulation. It can be understood that the control device may determine that the optical power corresponding to some services (for example, referred to as a service to be measured, M may be an integer greater than 1, for example) needs to be adjusted, or that the control device may determine that the optical power on an optical channel or an optical path where some services are located needs to be adjusted.

Illustratively, the control device may be, for example: centralized network elements, centralized control units, ACCs, etc.

For example, the control device may be, for example, the network management system in fig. 1, or the network management device in fig. 2. As another example, the control apparatus may be an apparatus in which the first device (e.g., NETWORK _ OD device) described above is deployed, or an apparatus in which the first device and the second device described above are deployed. It should be understood that the control device may include a plurality of modules, such as a light sensor module, a tuning data management module, a tuning algorithm module, a tuning control module, and the like, and the embodiments of the present application are not limited thereto.

It should be understood that the control device is only named for distinguishing different functions, and does not limit the protection scope of the embodiment of the present application.

The service referred to in the embodiments of the present application may represent a wavelength service or an optical layer service or represent a service that can be carried by an optical transport network. For example, it may be ethernet traffic, packet traffic, wireless backhaul traffic, etc. In the embodiment of the present application, traffic, wavelength traffic, and wavelength are sometimes used interchangeably, and all of them are used to mean wavelength traffic. For example, the traffic to be scheduled or the wavelength to be scheduled are both used to indicate the wavelength traffic on which the optical power scheduling or the optimized scheduling is to be performed. As another example, the affected traffic or affected wavelength is used to represent wavelength traffic affected by the modulation wave (i.e., the wavelength at which optical power modulation is performed). One service or one service may correspond to one OMS segment, or one or more wavelengths may be used in the same OMS segment.

Optionally, the control device may determine, according to the service optical performance data, a plurality of services to be scheduled that require optical power scheduling.

The control equipment can monitor the optical performance data of the whole network service in real time, analyze the monitored optical performance data of the service and determine the service needing to be optimized and tested.

Optionally, before step 410, the method 400 may further include step 401.

401, reporting service optical performance data to the control device by W stations, where W is an integer greater than 1 or equal to 1.

Correspondingly, the control device may determine M services to be scheduled according to the service optical performance data reported by the W sites.

The network element device may report the service optical performance data to the control device actively, and if the service optical performance data changes, the network element device may report the service optical performance data to the control device actively, so that the control device may determine whether optical power modulation and measurement are required according to the reported service optical performance data.

The network element device (e.g. W stations) collects the service optical performance data in real time in millisecond level of single station, and reports the optical performance data of single station to the control device. For example, the network element device may report the single-station single-board optical performance data to the control device through a path computation element communication protocol (PCEP). It is understood that the control device and each network element device may interact with each other through fields (e.g., extended fields) in the PCEP message. It should be understood that the transmission of the service optical performance data through the PCEP message is only an exemplary illustration and is not limited thereto, and any manner that can enable the control device to obtain the service optical performance data is applicable to the embodiment of the present application. It should be further understood that W sites represent sites reporting optical performance data of services, N testing sites represent sites where services to be tested are located or experienced, and W sites may include N testing sites, or W sites may also include a part of testing sites, which is not limited herein.

Illustratively, the extended path computation unit communication protocol may be, for example:

<PCEP_WDM_OP_RP_DATA>

<PCEP_STATIC_SRV_CFG>

<PCEP_LINK_KEY>

<PCEP_OTU_TX_OP_INFO>

<PCEP_WSS_OP_INFO>

<PCEP_EVOA_OP_INFO>

<PCEP_OA_OP_INFO>

<PCEP_WSS_OP_INFO>

<PCEP_EVOA_OP_INFO>

<PCEP_OA_OP_INFO>

<PCEP_FIU_OP_INFO>

<PCEP_OTU_RX_OP_INFO>

it should be understood that the form of the extended path computation unit communication protocol described above is merely an exemplary illustration provided for ease of understanding, and is not limited with respect to the specific form of the protocol. In future protocols, definitions or expressions used for meaning the same or for the same function are applicable to the embodiments of the present application.

The optical performance data may include, but is not limited to: the optical amplifier single board inputs/outputs the composite wave optical power, the single wave optical power, the optical amplifier gain, the EVOA attenuation value and the service BER.

In one possible implementation manner, the control device identifies a service to be scheduled that needs to perform optical power scheduling according to at least one of the following: whether the composite wave output power of each OMS section of the service deviates from a target value, whether OSNR attenuation (OSNRLOSS) of each service in the OMS is flat, and whether BER, OTU receiving end optical power and transmitting end optical power are abnormal for single-wave service is identified.

For example, in the case that the composite wave output power of each OMS segment of the service deviates from the target value, it may be determined that the service needs to perform optical power modulation. The optical power regulation or optimized regulation is carried out on the service, so that the performance of the service is improved, and the normal and stable operation of the system is ensured.

As another example, in a case where the BER of the single-wave service is high, for example, when the BER is higher than a preset threshold, it may be determined that the service needs to perform optical power modulation. The optical power regulation or optimized regulation is carried out on the service, so that the performance of the service is improved, and the normal and stable operation of the system is ensured. The preset threshold may be used to determine whether the optical power corresponding to the service needs to be measured. The value of the preset threshold is not limited in the embodiment of the application. For example, the preset threshold may be an empirical value, and may be determined based on statistical values of historical data, for example. For another example, the preset threshold may also be predefined, such as predefined by a protocol.

It should be understood that any way that the control device can identify the traffic requiring the optical power adjustment falls within the scope of the embodiments of the present application. For example, the control device may also monitor the system performance of the entire network in real time, and when the system performance is poor, the control device may select one or more sites to debug and observe whether the system performance of the entire network becomes good.

And 420, based on the M services to be tested, the control equipment sends the testing information to the N testing stations. Wherein. The debugging and testing information is used for parallel optical power debugging of N debugging and testing stations, the N debugging and testing stations belong to the stations where M services to be debugged are located, and N is an integer greater than 1 or equal to 1.

Accordingly, after each debugging station receives the debugging information, the optical power debugging can be performed based on the debugging information. For example, when the optical amplifier composite output power deviates from the target value, the optical amplifier gain or the EVOA attenuation value may be adjusted according to the tuning information. For another example, when the output optical power of the optical amplifier single wave deviates from the target value, the WSS attenuation value may be adjusted according to the measurement information.

The W sites and the N testing sites have no strict corresponding relation, the testing sites represent sites where the service to be tested is located or experienced sites, and the W sites represent sites which actively report the service optical performance data. In one possible scenario, the W sites may include N survey sites.

By the embodiment of the application, parallel debugging and testing can be realized. The control equipment can firstly identify the service needing to be optimized and tested, then optimize the service needing to be optimized and tested and send the testing information to each testing station, so that each testing station can conduct parallel testing according to the testing information. The control device may centrally control: the system has the advantages that multiple services, multiple faults (namely, multiple services need to be optimized, debugged and tested) and multiple debugging and testing stations can realize automatic parallel optimization, debugging and testing of multiple services, multiple OMS sections and multiple debugging and testing stations, supports multiple service and multiple fault scenes, and is suitable for more debugging and testing scenes. In addition, debugging and testing can be optimized rapidly, and debugging and testing stations are tested in parallel as many as possible, so that the optimization debugging and testing efficiency is improved, and the requirements of customers for rapid automatic optimization debugging and testing are met as much as possible.

In the embodiment of the present application, parallel testing is not limited to that the testing time of a plurality of testing stations is always the same. And performing parallel debugging, namely, the control device can simultaneously send debugging information to a plurality of debugging sites in one message, and the plurality of debugging sites can respectively perform debugging based on the received debugging information. Alternatively, parallel testing, it is understood that multiple OMS segments or multiple testing stations may be tested in parallel.

Optionally, the control device may send T times of the debugging information to the N debugging stations, where T is an integer greater than 1 or equal to 1. That is, the control device may send one or more pieces of commissioning information to the N commissioning stations.

For example, the control device sends the tuning and testing information to N tuning and testing stations, and after the N tuning and testing stations tune and test according to the tuning and testing information, if each OMS section achieves the target power, the control device may no longer send the tuning and testing information to the N tuning and testing stations.

For another example, the control device sends the tuning and testing information to N tuning and testing stations, and after the N tuning and testing stations tune and test according to the tuning and testing information, if each OMS section does not reach the target power, the control device may continue to send the tuning and testing information to the N tuning and testing stations. The scheduling information transmitted each time may be the same or different, and is not limited thereto. For example, each time a commissioning station commits, the control device may recalculate commissioning information. For another example, each time the debugging station finishes debugging, the control device does not calculate the debugging information any more, and may transmit the debugging information based on the first calculation or may transmit the debugging information based on a small step length. As another example, the commissioning site may commission multiple times based on the commissioning information.

In another example, the control device sends multiple times of debugging and testing information to the N debugging and testing stations, and each debugging and testing can be small-step debugging and testing, so that the influence of the influenced waves is reduced, and the debugging and testing safety is improved.

It can be understood that in the embodiment of the present application, N modulation and measurement sites may modulate and measure optical power once, or N modulation and measurement sites may perform optical power modulation and measurement once; alternatively, the N modulation sites may modulate optical power for multiple times, or the N modulation sites may perform multiple optical power modulations.

Alternatively, the control device may implement tuning algorithm modeling. Specifically, the control device may calculate some commissioning information by modeling the physical parameters of the optical performance, such as: the target optical power of the service to be regulated and tested, the optimal regulating step length of the service to be regulated and tested, the regulating quantity of each old wave of the affected service and the like are provided for the regulating and optimizing control module to carry out parallel regulation and testing.

For ease of understanding, the process of tuning algorithm modeling of the control device is illustrated in connection with FIG. 5.

FIG. 5 is a single OMS segment model. Two reconfigurable optical add-drop multiplexer (ROADM)/fixed optical add-drop multiplexer (FOADM) nodes can form an OMS section. In the OMS section, optical layer devices, i.e., devices capable of processing optical layer signals, may include, for example but are not limited to: optical Amplifiers (OA), optical add-drop multiplexers (OADM) (e.g., ROADM/FOADM). OA, also known as Optical Line Amplifier (OLA), is mainly used to amplify optical signals to support transmission over longer distances while ensuring specific performance of the optical signals. OADMs are used to spatially transform optical signals so that they can be output from different output ports (sometimes also referred to as directions).

The devices for mutual influence between waves in the OMS section mainly comprise optical amplifiers (hole burning effect) and optical fibers (Raman effect). Optical Performance Monitors (OPMs) are distributed at the head and end nodes of the OMS segment, and can monitor single-wave optical power at the head and end nodes. That is, the optical performance monitor may monitor the single-wave optical powers at the two nodes, i.e., site a (or network element a) and site B (or network element B), of the OMS _ head node and OMS _ tail node shown in fig. 5. When the output power of the optical amplifier composite wave deviates from a target value, the optical amplifier gain or the EVOA attenuation value can be adjusted; the WSS attenuation value can be adjusted when the output optical power of the optical amplifier sheet deviates from a target value. And when the optical power of each OMS section reaches the target optical power, the service performance is indicated to be excellent, and the debugging is completed.

Before the control equipment sends the debugging information, some debugging information can be calculated, so that the debugging station can carry out reasonable debugging. The following describes the scheme of the scheduling information in detail from several aspects. It should be understood that the following aspects may be used independently or in combination with each other, and are not limited thereto.

Aspect 1: the control device may calculate a target optical power for the traffic to be scheduled.

The target optical power represents a nominal optical power value or an expected optical power, or an expected optical power after the modulation and measurement of the service to be modulated. And the control equipment calculates the target optical power of the service to be measured, and when each OMS section achieves the target power, or the optical power of each OMS section is adjusted to the target optical power, the measurement is finished.

Alternatively, the control device may calculate the target optical power of the main optical path or the combined wave and the target optical power of the single wave, respectively.

As an example, the target optical power of the main optical path may be based on: and the main optical path on the OMS section is obtained by calculation according to the principle of optical amplifier gain compensation circuit attenuation. It can be understood that the target optical power of the main optical path on each OMS section is calculated based on the attenuation of the optical amplifier gain compensation circuit.

As yet another example, the target optical power for a single wave is: and calculating the OMS originating single-wave optical power of OSNR attenuation equalization by the current monitoring value. It can be understood that the single-wave service calculates the OMS-originating single-wave optical power with OSNR fading balance as the target optical power based on the current monitored value.

Aspect 2: the control device may calculate the adjustment sum.

Considering multi-service parallel debugging, the control device can calculate the total adjustment amount of the OMS section, and further can determine the adjustment amount of each debugging station.

As an example, the total amount of absolute adjustment of the OMS segment is calculated.

For example, the total amount of absolute adjustment of the main light path on the OMS segment may be: difference between optical amplification gain and composite attenuation. That is, the difference between the optical amplification gain on the OMS section and the optical path attenuation value on the main optical path is calculated, which is the optical path absolute adjustment total.

As another example, the total amount of single wave absolute modulation on the OMS section may be: the target optical power of the single wave minus the value of the actual optical power of the single wave. That is, a value of the target optical power of the single wave on the OMS section minus the actual optical power of the single wave is calculated, which is the single wave absolute adjustment amount.

Optionally, the control device may determine the adjustment amount of each tuning and measuring station according to the total absolute adjustment amount of the OMS section. To facilitate understanding, an example is enumerated.

Assuming that a service to be debugged passes through an OMS section, a debugging site on the OMS section where the service to be debugged is located comprises: and the adjusting and testing sites A and B assume that the absolute adjusting total amount of the OMS section is P. For example, the adjustment amounts for station A and station B may be P/2, respectively. For another example, the ratio of the adjustment amounts of modulation site a and modulation site B is a preset ratio, such as modulation site a with adjustment amount (a × P) and modulation site B with adjustment amount ((1-a) × P), or modulation site a with adjustment amount ((1-B) × P) and modulation site B with adjustment amount (B × P). a. b is a number of 0 or more and 1 or less. It should be understood that the adjustment amounts of the adjustment station a and the adjustment station B are not limited to the respective amounts.

As yet another example, a relative adjustment total for the OMS segment is calculated.

For example, the relative adjustment amount of a certain tuning site may be: the total absolute adjustment for that station minus the cumulative adjustment for all stations upstream of that station.

Upstream or downstream: data is transmitted from a source device a to a destination device B, and passes through a device M, and a device M point is located between the device a and the device B point in a data transmission direction, so that the device a is in an upstream direction of the device M, and the device B is in a downstream direction of the device M.

In this example, the control device may determine the adjustment amount of each tuning station according to the relative adjustment total amount of the OMS section. To facilitate understanding, an example is enumerated.

Assuming that a service to be debugged passes through an OMS section, a debugging site on the OMS section where the service to be debugged is located comprises: and (3) the adjusting and measuring station A and the adjusting and measuring station B assume that the total relative adjusting quantity of the OMS section is P ', for example, the ratio P' of the adjusting quantity of the adjusting and measuring station A to the adjusting quantity of the up-adjusting and measuring station B. Then, the adjustment amount of modulation site a may be (x × P '), and the adjustment amount of modulation site B may be (P '), or one of the modulation sites may be modulated in small steps, for example, 0.5db, and the adjustment amount of the other modulation site may be determined according to P ' and 0.5. It should be understood that the adjustment amounts of the adjustment station a and the adjustment station B are not limited to the respective amounts.

Considering that the optical power changes after the optical power at the upstream of the service is adjusted and the optical power at the downstream of the service also changes correspondingly, the adjustment quantity at the downstream site can be obtained by subtracting the adjustment quantity accumulated by all the OMS from the adjustment quantity of the optical power at each wave at the downstream site through the hedging of the upstream and downstream adjustment quantities, and the separate truncation operation is not needed.

Based on the scheme, the main optical path and the single-wave step length are independently calculated and decoupled with each other, so that the repeated calculation of the combined-wave power regulating quantity can be avoided, the debugging times are reduced, and the debugging efficiency is further improved.

Optionally, in this embodiment of the present application, the adjustment amount of each debugging station may be determined separately according to the absolute adjustment total amount of the OMS section or the relative adjustment amount of the OMS section; alternatively, the adjustment amount of each tuning and measuring station may be determined simultaneously according to the absolute adjustment total amount of the OMS section and the relative adjustment amount of the OMS section, which is not strictly limited.

Aspect 3: the control device may calculate an adjustment step size of the service to be adjusted.

For example, the control device may calculate an optimal adjustment step size for the traffic to be adjusted.

It can be understood that if all the OMS sections are issued in parallel according to the minimum step length, the influence on other influenced waves is small, the safety is high, and the debugging efficiency is improved a little; if the maximum step length of each OMS section is sent down in parallel, service interruption may be caused if the debugging values of all debugging stations are not effective simultaneously and only effective in the same direction. Therefore, the limitation of the parallel-modulation co-modulation step size can be considered. In the embodiment of the application, the safety influence of the debugging and the testing on other waves and the requirements of the debugging and the testing performance are considered, and the single station (OMS) step length constraint and the inter-station (OCH level) equidirectional debugging and testing step length constraint are considered and issued in parallel according to the OMS section, so that the influence on other waves is controllable, and the parallel debugging and testing performance is high.

A possible implementation mode can give consideration to the safety influence of the regulation and the measurement on other waves and the requirement of the regulation and the measurement performance, and the regulation and the measurement step length of each regulation point is issued in parallel according to the OMS section which gives consideration to the single-station step length constraint and the inter-station equidirectional regulation and measurement step length constraint.

Example 1, single station (OMS) step size constraint (i.e., OMS segment dimension): and the forward and reverse offset of the debugging step length of a plurality of services to be debugged on the same debugging site through the OMS section does not exceed a third threshold value.

The third threshold may be used to determine whether the modulation step size on the modulation station is appropriate.

For example, the third threshold may be used to compare the modulation step size of the combined wave at the modulation station with the modulation step size of the single wave at the modulation station. If the step value is too large and exceeds the third threshold value after the adjusting and measuring step lengths of the combined waves of the services to be adjusted and measured on the adjusting and measuring site are offset in the forward and reverse directions, the adjusting and measuring step lengths of the combined waves of the services to be adjusted and measured on the adjusting and measuring site are not appropriate or are not optimal. Similarly, if the step value is too large and exceeds the third threshold value after the forward and reverse cancellation of the measurement step sizes of the single waves of the multiple services to be measured on the measurement site, it indicates that the measurement step sizes of the single waves of the multiple services to be measured on the measurement site are not appropriate or optimal.

The embodiment of the present application has been described with reference to a third threshold as an example, which is not limited to this. For example, two third threshold values may also be included, where one third threshold value is used to compare with the modulation step size of the combined wave on the modulation site, and the other third threshold value is used to compare with the modulation step size of the single wave on the modulation site.

The embodiments of the present application are not limited to the case of equality. The third threshold may be used for comparing with the tuning and measuring step length of the combined wave on the tuning and measuring site, and when the step value after the forward and reverse offsets of the tuning and measuring step length of the combined wave of the multiple services to be tuned and measured on the tuning and measuring site is equal to the third threshold, the tuning and measuring step length of the combined wave of the multiple services to be tuned and measured on the tuning and measuring site may be considered to be appropriate, or the tuning and measuring step length of the combined wave of the multiple services to be tuned and measured on the tuning and measuring site may also be considered to be inappropriate.

The value of the third threshold is not limited in the embodiment of the present application. For example, the third threshold value may be an empirical value, and may be determined based on statistical values of historical data, for example. For another example, the third threshold may also be predefined, such as predefined by a protocol.

Example 2, inter-station (OCH level) step size constraint (i.e. OCH traffic dimension): the same service does not exceed the fourth threshold value through the same-direction accumulated step length on all network elements.

The fourth threshold may also be used to determine whether the modulation step length of the service to be modulated on each modulation station is appropriate.

For example, the fourth threshold value may be used to compare the cumulative step size in the same direction for the same service across all regulatory sites. If the cumulative step length of the same service passing through all the debugging sites in the same direction is too large and exceeds the fourth threshold value, the debugging step length of the service to be debugged on each debugging site is not appropriate or optimal.

The embodiments of the present application are not limited to the case of equality. When the cumulative step length of the same service passing through all the debugging sites in the same direction is equal to the fourth threshold value, the debugging step length of the service to be debugged on each debugging site may be considered to be improper, or the debugging step length of the service to be debugged on each debugging site may also be considered to be proper.

The value of the fourth threshold value is not limited in the embodiment of the present application. For example, the fourth threshold value may be an empirical value, which may be determined, for example, from statistical values of historical data. For another example, the fourth threshold value may also be predefined, such as predefined by a protocol.

Based on the above examples 1 and 2, the cumulative step size of single-station multi-service (including the combined wave and single wave adjustment amount) and the cumulative step size of the OCH service in the same direction of each tuning station can be considered comprehensively. For example, if the modulation step lengths of a plurality of services to be modulated on the same modulation site through the OMS section are cancelled in the forward and reverse directions and then exceed the third threshold, and the cumulative step length of the same service in the same direction on all network elements exceeds the fourth threshold, the adjustment amounts of all modulation sites can be adjusted in proportion to determine the optimal modulation step length of the main optical path (i.e., the combined wave) and the single wave of the single-station modulation site at this time. For another example, if the modulation step lengths of a plurality of services to be modulated on the same modulation site through the OMS section exceed the third threshold after being cancelled in the forward and reverse directions, or the cumulative step length of the same service passing through all network elements in the same direction exceeds the fourth threshold, the adjustment amounts of all modulation sites may be adjusted in proportion to determine the optimal modulation step lengths of the main optical path (i.e., the combined wave) and the single wave of the single-station modulation site at this time.

Optionally, the control device may also issue multiple times of debugging information. For example, the control device may calculate a better or optimal adjustment step size for the traffic to be scheduled each time the scheduling information is issued, as calculated above according to example 1 and example 2. For another example, when the adjustment is performed in a multi-adjustment mode, the adjustment and the measurement can be performed in a single adjustment mode by using a small step length, so that the adjustment and the measurement safety can be improved.

Based on the scheme, the single OMS step length constraint and the OCH level equidirectional debugging step length constraint are considered, the small step length debugging and the small step length multiple-time issuing debugging and testing are carried out, the phenomenon that the performance fluctuation is too large due to too large single issuing of the regulating quantity is avoided, and therefore the debugging and testing safety can be improved. In addition, the scheme of the aspect 3 can provide hedging guarantee, namely parallel debugging realizes small-step hedging of upstream and downstream power, and fluctuation is avoided. In addition, the scheme of aspect 3 may also provide a homodromous validation guarantee, that is, the homodromous step size constraint is limited in consideration of the asynchronous network element communication.

Aspect 4: the control device may calculate the adjustment step size for the affected service.

The affected service, or the affected wavelength service or the affected old wave service, is used to indicate the wavelength service affected by the modulation wave (i.e., the wavelength at which the optical power modulation is performed).

For example, the control device may calculate an optimal adjustment step size for the affected traffic.

In the embodiment of the present application, in order to ensure that the performance of the affected old wave does not deteriorate (e.g., OSNR deterioration), the pre-adjustment amount of the optical power of the old wave can be calculated by comparing the deterioration amount of the old wave before and after the adjustment measurement.

The adjusting value of the affected old wave can not be accurately calculated before the first adjusting and measuring of the service to be adjusted and measured is carried out, in order to improve the precision, the degradation amount of the affected old wave can be calculated after the first adjusting and measuring of the wave to be adjusted and measured is effective, and the degradation amount of the affected old wave is not degraded through repeated iteration until the affected old wave, so that the accuracy of the pre-adjustment amount of the optical power of the affected old wave can be improved.

Illustratively, historical values of optical amplifier ONSR attenuation of the affected old wave service at multiple modulation and measurement sites are recorded, after the parallel service modulation and measurement are effective for the first time, real-time values of optical amplifier ONSR attenuation of the affected old wave service at the multiple modulation and measurement sites can be obtained, a difference between the real-time values and the real-time values is calculated, and a modulation and measurement step length of a single wave of the affected old wave service at the multiple modulation and measurement sites is determined.

For example, the modulation step size of the single wave of the affected old wave service at the plurality of modulation sites may be: the difference between the historical values of the optical amplifier ONSR attenuation of the affected old wave service and the real-time values of the optical amplifier ONSR attenuation of the affected old wave service. Wherein the optical amplifier ONSR attenuation history value of the affected old wave service represents: and (3) historical values of optical amplifier ONSR attenuation of the affected old wave service at a plurality of debugging sites, such as recorded optical amplifier ONSR attenuation of the affected old wave service at the plurality of debugging sites before the first parallel service debugging. The optical amplifier ONSR attenuation real-time values of the affected old wave service represent: and after the first parallel service debugging and testing is effective, the real-time values of the optical amplifier ONSR attenuation of the affected old wave service at the plurality of debugging and testing sites.

Based on the scheme, the reliability and the safety of parallel debugging and testing can be ensured, the influence on the influenced old wave service can be reduced, the safety of the influenced old wave service is ensured as much as possible, and the overall performance of the system is improved.

Aspect 5: and adjusting the format of the information.

Optionally, after the control device calculates the tuning information, the tuning values or tuning amounts may be transmitted in parallel to the N tuning sites according to the tuning positions and the tuning step lengths, so as to perform optical power tuning or optimal tuning or optical layer tuning at the tuning sites.

Illustratively, a PCEP path computation LSP update request (pcup) message may be extended: and packaging the debugging information (or multi-fault information) of the debugging in one message and sending the information to the same destination site. The commissioning information may include, for example, but is not limited to, at least one of the following:

light amplifier gain, light amplifier gain adjustment quantity and adjustment points;

EVOA attenuation, light attenuation adjustment quantity and adjustment points;

the method comprises the steps of measuring the channel number of a wave to be modulated, the WSS single wave regulating quantity and a regulating point;

affected wave channel number, WSS single wave regulating quantity and regulating point.

Wherein, the regulation point represents the regulation and measurement station. By the adjusting point information, which adjusting stations correspond to the corresponding adjusting quantity can be known.

Wherein, the single wave regulation point needs to be carried with the LSP attribute.

In addition, there are how many affected old waves in an OMS section that need to be preconditioned. Illustratively, the adjustment step size for each affected old wave may be determined based on the scheme of aspect 4.

Illustratively, the commissioning information includes: light amplifier gain, light amplifier gain adjustment amount and adjustment point. Accordingly, upon receiving the tuning information, the tuning point (i.e., the tuning site) can determine what the amount of tuning of the main beam or the multiplex is based on the tuning information. In other words, the adjusting point (i.e., the adjusting station) adjusts the optical power of the main optical path or the combined wave based on the optical amplifier gain adjusting amount.

Illustratively, the commissioning information includes: the channel number of the wave to be measured, the WSS single wave regulating quantity and the regulating point. Accordingly, after the adjusting point (i.e., the adjusting station) receives the adjusting information, it can determine the adjusting wave and the adjusting amount of the adjusting wave based on the adjusting information. In other words, the adjustment point (i.e., the adjustment station) adjusts the optical power of the measurement wave based on the WSS single-wave adjustment amount.

Illustratively, the commissioning information includes: affected wave channel number, WSS single wave regulating quantity and regulating point. Accordingly, after the adjustment point (i.e., the adjustment station) receives the adjustment information, it can determine the affected old wave and the adjustment amount of the affected old wave based on the adjustment information. In other words, the adjusting point (i.e. the adjusting station) adjusts the optical power of the affected old wave based on the single-wave adjustment amount of the WSS, so as to reduce the effect of the adjusting wave on the affected old wave and ensure the safety of the affected old wave as much as possible.

It should be understood that the above examples are illustrative only and are not limiting.

The above five aspects describe the scheme related to the measurement information, and the embodiments of the present application are not limited thereto. For example, the above-described aspects may be used independently or in combination with each other. For another example, the control device may also determine more tuning information, so that the tuning station may perform optical power tuning or optimize tuning according to the tuning information.

Optionally, in this embodiment of the present application, the control device may further query the relevant optical power information of the modulation service and the affected service.

After the debugging station optimizes debugging according to the debugging information, the response of completing the debugging can be fed back to the control equipment, for example, the response of completing the debugging can be recorded. Accordingly, the control device may query the relevant optical power information of the modulation service and the affected service according to the fed-back modulation response, so as to determine whether the optimized modulation is completed or whether further modulation is needed, and so on. Specifically, the following two schemes may be included.

Scheme 1: after each commissioning, the control device queries the commissioning service and the relevant optical power information of the affected services.

In the scheme, after the debugging station finishes the debugging, the debugging response of the debugging completion can be fed back to the control equipment.

In one possible scenario, after receiving the modulation response, the control device actively queries the modulation service and the related optical power information of the affected service, and may proceed with the processing of aspects 1 to 5. And finally, the difference between the service composite wave or single wave optical power of each OMS section and the target optical power is within a certain numerical range, thereby indicating that the service optimization regulation is completed.

In another possible situation, after receiving the debugging response, the control device actively queries the related optical power information of the debugging service and the affected service, and the difference between the combined wave or single wave optical power of each OMS section service and the target optical power is within a certain numerical range, thereby indicating that the service optimization debugging is completed.

Illustratively, when the difference between the combined wave or single wave optical power of each OMS section service and the target optical power is within 0.5db, it indicates that the service optimization debugging is completed. It should be understood that 0.5db is merely an exemplary illustration and that the embodiments of the present application are not limited thereto.

Based on the scheme 1, the debugging result can be monitored in real time, so that the overall debugging efficiency can be improved, and unnecessary debugging and time cost and calculation cost brought by unnecessary debugging are reduced.

Scheme 2: and under the condition of meeting a certain condition, the control equipment inquires the relevant optical power information of the debugging service and the affected service.

That is, the control device does not need to query the modulation service and the relevant optical power information of the affected service every time or after every cycle of modulation at the modulation site. The control equipment can inquire and debug the relevant optical power information of the service and the affected service under the condition of meeting a certain condition, thereby reducing the waste of time and the influence on the service.

In one possible case, the control device queries the relevant optical power information of the modulation service and the affected service when the modulation frequency reaches a preset frequency.

For example, the control device may query the relevant optical power information of the modulation service and the affected service when the modulation frequency of any modulation station reaches a preset frequency.

For another example, the control device may query the modulation service and the related optical power information of the affected service when the total number of modulation times of all modulation sites reaches a preset number.

It should be appreciated that the preset number of times may be used to determine whether the control device is to query the associated optical power information for the commissioning traffic and the affected traffic.

For example, the preset number may be used for comparison with the number of tests at any one test station, or the number of tests at all test stations. For example, taking any one of the modulation sites as an example, if the modulation times of any one of the modulation sites reaches a preset number, after the modulation is finished, the control device may query the modulation service and the optical power information related to the affected service. For another example, taking all the modulation sites as an example, if the modulation times of all the modulation sites reach the preset times, after the modulation is finished, the control device may query the modulation service and the optical power information related to the affected service.

It should be understood that the preset number of times of comparison with the number of times of adjustment at any one adjustment station and the preset number of times of comparison with the number of times of adjustment at all the adjustment stations may be different or the same, and there is no strict relationship between the two. In other words, a preset number of times can be set, and the preset number of times is used for comparing with the testing number of any testing station; alternatively, a preset number of times may be set, and the preset number of times is used for comparison with the number of times of debugging of all debugging stations.

The value of the preset times is not limited in the embodiment of the present application. For example, the preset number of times may be an empirical value, and may be determined based on statistical values of historical data, for example. For another example, the preset number of times may also be predefined, such as predefined by a protocol.

In another possible case, the control device queries the relevant optical power information of the modulation service and the affected service in case the modulation measurement reaches a preset modulation measurement.

For example, in a case that the modulation measurement of any modulation site reaches the first threshold, the control device queries the modulation service and the related optical power information of the affected service.

For another example, the control device may query the modulation service and the related optical power information of the affected service when the modulation total amount of all modulation sites reaches the second threshold.

It should be appreciated that the preset modulation measurements (e.g., the first threshold value and the second threshold value) may be used to determine whether the control device is to query the modulation service and the affected service for relevant optical power information.

For example, a first threshold value may be used to compare to the modulation measurements at any one modulation site, or a second threshold value may be used to compare to the total modulation measurements at all modulation sites. For example, taking any one of the modulation sites as an example, if the modulation measurement of any one of the modulation sites reaches the first threshold, after the modulation is finished, the control device may query the modulation service and the optical power information related to the affected service. For another example, taking all the modulation sites as an example, if the modulation total amount of all the modulation sites reaches the second threshold, after the modulation is finished, the control device may query the modulation service and the optical power information related to the affected service.

It should be understood that the first threshold value compared to the modulation measurement at any one modulation site and the second threshold value compared to the total modulation measurement at all modulation sites may be different or the same, and there is no strict relationship between the two. In other words, a first threshold value may be set, and the first threshold value is used for comparing with the measured value of any measured station; alternatively, a second threshold value may be set which is used to compare with the total measured amount for all the stations.

The value of the preset tuning measurement is not limited in the embodiment of the present application. For example, the preset tuning measure may be an empirical value, which may be determined, for example, from statistical values of historical data. For another example, the preset tuning measure may be predefined, such as defined by a protocol.

The above description exemplarily understands the two cases, and the embodiment of the present application is not limited thereto. For example, the two cases may be used alone or in combination, and are not limited thereto.

In the scheme 2, under the condition that a certain condition is met, the control device queries the modulation service and the related optical power information of the affected service, and can continue the processing from the aspect 1 to the aspect 5, the actual power value of the service to be modulated slowly approaches to the target value, and finally the difference between the composite wave or single wave optical power of each OMS section service and the target optical power is within a certain numerical range, thereby indicating that the service optimization modulation is completed. Or, under the condition of meeting a certain condition, the control device inquires the related optical power information of the debugging service and the affected service, and the difference between the combined wave or single wave optical power of each OMS section service and the target optical power is within a certain numerical range, thereby indicating that the service optimization debugging is completed.

In the scheme 2, the debugging station can feed back the debugging response after debugging each time, and can feed back the debugging response again under the condition of meeting a certain condition.

Based on the scheme 2, the debugging step length of the service to be debugged can be calculated without the scheme based on the aspect 3, and small step length debugging can be used in each debugging, so that the overlarge regulating quantity of single debugging can be avoided, and the debugging safety can be improved. In addition, the time cost and the calculation cost caused by frequent inquiry of real-time optical power by the control device can be reduced. Especially, in a scene that the network topology is large and the span of the service to be measured and the affected service passing through the network element is large, the automatic parallel optimization measurement mode that the small step length of each station is used for multiple times of measurement is considered, a certain condition (such as after a certain measurement is accumulated) is met for feedback, and the time consumed by multiple real-time optical power query of the control equipment is reduced. Meanwhile, each debugging and testing station is issued according to a small step length, and the adjustment quantity of the affected service can be carried by issuing the adjustment quantity for the second small step length, so that the safety of the old wave service is ensured.

The above details describe the scheme of parallel debugging proposed in the embodiments of the present application. The parallel optimization debugging method can be applied to a service issuing scene, can automatically optimize debugging and test based on low-power parallel wave-adding supplement optimization debugging and test, and can quickly improve service performance. The parallel optimization debugging method can also be applied to a rerouting scene, and based on low-power parallel wave-adding supplement optimization debugging, new services can be quickly opened while ensuring the safety of old waves. By the embodiment of the application, the service optimization debugging scheme under the complex scenes of multi-wavelength service, multi-point faults and single-wave and main optical path multi-point coupling degradation can be provided, so that the method and the device are suitable for more debugging scenes. Based on the parallel debugging scheme provided by the embodiment of the application, the problem of service interruption caused by single-point serial debugging can be solved. In addition, in some embodiments, the influence of the upstream and downstream OMS sections is considered in a centralized manner, the relative regulating quantity of each debugging station is calculated, the upstream and downstream regulating quantities naturally offset, multi-service (for example, control equipment controls multi-service) is realized through centralized protocol control, and the debugging efficiency and the safety are greatly improved by the multi-OMS section and the multi-debugging station for parallel optimization debugging.

In the following, for ease of understanding, a possible complete flow is described in connection with specific examples.

Fig. 6 shows a schematic diagram suitable for use in embodiments of the present application.

Assuming that the wavelength service needs to perform power regulation and measurement, such as service performance degradation caused by optical fiber cutting, optical fiber degradation, station insertion loss degradation, manual misoperation and the like, the wavelength service needs to perform power regulation and measurement. A possible flow of optical power regulation is described below in connection with fig. 6.

As shown in fig. 6, it is assumed that four stations and one control device are included, and the stations are respectively denoted as a station a, a station B, a station C, and a station D for distinction. The control device may be deployed in an independent server, or may be deployed in a network element device with strong capability (e.g., any one of site a, site B, site C, and site D). The control apparatus has a first device (e.g., a NETWORK _ OD device) deployed therein and enabled to perform automated optimization commissioning services.

Assume that there are four services in the network: legacy 1 (i.e., legacy service 1): site a-site B-site D; legacy 2 (i.e. legacy service 2): site B-site C; legacy 3 (i.e. legacy service 3): site a-site B; legacy 4 (i.e. legacy service 4): site a-site B-site C. The old waves 1 and 2 are affected waves (i.e., affected services), and for the purpose of distinction, the old waves 1 are marked as affected waves 1, and the old waves 2 are marked as affected waves 2. The old waves 3 and 4 are to-be-modulated waves (i.e. to-be-modulated services), and for the purpose of differentiation, the old waves 3 are recorded as to-be-modulated waves 3, and the old waves 4 are recorded as to-be-modulated waves 4. It should be understood that fig. 6 is merely an illustration, and that in practice there may be more wavelength traffic or more sites.

One possible completion flow is described below.

Step 1, controlling the automatic real-time monitoring of the optical performance data of the whole network of equipment: and acquiring service optical performance data in real time at the single station millisecond level of the equipment.

In a possible implementation manner, the network element device may report the optical performance data of the single-station board to the control device through the extended path computing unit communication protocol. It is understood that the control device and each network element device may interact with each other through fields (e.g., extended fields) in the PCEP message.

Taking fig. 6 as an example, in step 1, each station, such as station a, station B, station C, and station D, collects service optical performance data in milliseconds, and reports the collected service optical performance data to the control device.

As for the service optical performance data reported by the station, reference may be made to the description of step 401 in the method 400, which is not described herein again.

And 2, identifying the service to be debugged, which needs to be subjected to optical power debugging, by the control equipment.

In step 2, the control device may automatically identify a batch service with degraded performance of the entire network based on the service optical performance data acquired in step 1.

For identifying, by the control device, a service to be scheduled that needs to perform optical power scheduling based on the service optical performance data, reference may be made to the description in the method 400, and details are not described here again.

And 3, calculating the target optical power of the service to be regulated by the control equipment.

Taking fig. 6 as an example, a wave 1 to be measured (i.e., a service 1 to be measured) and a wave 2 to be measured (i.e., a service 2 to be measured) pass through the OMS section 1 and the OMS section 2. And calculating the target optical power of the main optical path on the basis of the optical amplifier gain compensation circuit attenuation of the main optical path on each OMS section, and calculating the OMS originating single-wave optical power with OSNR attenuation balance as the target optical power by the single-wave service based on the current monitoring value.

After the control device determines the target optical power, the measured position and the corresponding measured total amount can be calculated.

And 4, analyzing and calculating the debugging position and the debugging total amount by the control equipment debugging strategy.

As an example, the OMS segment absolute adjustment total is calculated.

Taking fig. 6 as an example, a wave 1 to be measured (i.e., a service 1 to be measured) and a wave 2 to be measured (i.e., a service 2 to be measured) pass through the OMS section 1 and the OMS section 2. The total amount of absolute adjustment for each OMS section is calculated independently.

As yet another example, the OMS segment relative adjustment totals are calculated.

This will be explained with reference to fig. 7.

Adjusting and measuring site A relative adjusting total quantity delta P1 (adjusting and measuring site A absolute adjusting total quantity) - (all adjusting points in front of adjusting and measuring site A accumulated total quantity) is adjusting and measuring site A absolute adjusting total quantity;

adjusting and measuring station B relative adjusting total quantity delta P2 ═ total (adjusting and measuring station B absolute adjusting total quantity) - (all adjusting points in front of adjusting and measuring station B cumulative total) ═ total (adjusting and measuring station B absolute adjusting total quantity) - (adjusting and measuring station A adjusting total quantity);

and adjusting and measuring site C relative adjusting total quantity delta P3 (adjusting and measuring site C absolute adjusting total quantity) - (all adjusting points in front of adjusting and measuring site C cumulative total quantity) or (adjusting and measuring site C absolute adjusting total quantity) - (adjusting and measuring site A adjusting total quantity) - (adjusting and measuring site B adjusting total quantity).

Considering that the optical power changes after the optical power at the upstream of the service is adjusted and the optical power at the downstream of the service also changes correspondingly, the adjustment quantity at the downstream site can be obtained by subtracting the adjustment quantity accumulated by all the OMS from the adjustment quantity of the optical power of each wave at the downstream site through the hedging of the upstream and downstream adjustment quantities, so that the separate truncation operation is not needed.

After the control equipment determines the total debugging quantity, the debugging position and the debugging step length of each debugging station can be analyzed.

And 5, analyzing and calculating the debugging position and the debugging step length by the control equipment debugging strategy.

The control equipment can analyze and calculate the debugging position, the debugging step length of the service to be debugged and the debugging step length of the affected service through the debugging strategy according to the calculated service target power and the expected effect. Described separately below.

Firstly, the debugging step length of the service to be debugged is related.

The control device may calculate an optimal adjustment step size for the service to be adjusted.

Example 1, single station (OMS) step size constraint (i.e., OMS segment dimension): the forward and reverse offset of the debugging step length of a plurality of services to be debugged on the same site through the OMS section does not exceed a third threshold value.

Site a in fig. 6 is taken as an example. The wave 1 to be measured (i.e. the service 1 to be measured) and the wave 2 to be measured (i.e. the service 2 to be measured) are not more than the third threshold value after the wave combining regulation step length is counteracted in the forward and reverse directions on the site a, and the wave 1 to be measured (i.e. the service 1 to be measured) and the wave 2 to be measured (i.e. the service 2 to be measured) are not more than the third threshold value after the wave combining regulation step length is counteracted in the forward and reverse directions on the site a.

Taking fig. 8 as an example, a wave 2 to be measured (i.e., a service 2 to be measured) passes through a site a, a site B, and a site C, it is assumed that the measurement step lengths of the service passing through the 3 sites are respectively 0.6db, -1.2db, and 0.6db, and it is assumed that the fourth threshold is 1.6 db. Then, the forward cumulative step value is 1.2db (i.e., 0.6+0.6 ═ 1.2), and the reverse cumulative step value is 1.2db (i.e., 1.2). 1.2db is less than 1.6db, so the equidirectional accumulated step length does not exceed the fourth threshold.

The above is only a simple description, and for the specific measurement step size of the service to be measured, reference may be made to the description of aspect 3 in the method 400, and details are not described here again.

And II, adjusting and measuring the step size of the affected service.

The control device may calculate an optimal adjustment step size for the affected service.

In the embodiment of the present application, in order to ensure that the performance of the affected old wave does not deteriorate (e.g., OSNR deterioration), the amount of pre-adjustment of the old wave power may be calculated by comparing the amount of deterioration of the old wave before and after the adjustment measurement.

For improving the precision, for example, the degradation amount of the old wave can be calculated after the first modulation and measurement of the wave to be modulated becomes effective, and through repeated iteration, the degradation of the old wave is not caused until the old wave is not degraded, and the corresponding old wave pre-modulation amount is relatively accurate.

Illustratively, historical attenuation values of old wave service optical amplifiers ONSR are recorded at a site a and a site B, and after the first parallel service modulation and detection takes effect, a real-time value of the old wave service optical amplifiers ONSR after attenuation can be obtained, a difference between the two values is calculated, and the modulation and detection step length of the affected service at the single wave of the site a and the site B is determined.

The above is only a simple description, and for the specific step size for the measurement of the affected service, reference may be made to the description of the aspect 4 in the method 400, which is not described herein again.

And 6, the control equipment parallelly transmits the adjusting value (or adjusting and measuring information) to the adjusting and measuring station (or the NE _ OD device configured in the adjusting and measuring station) according to the adjusting and measuring position and the adjusting and measuring step length.

The control device calculates: after the optical power adjustment amounts of the waves 1 and 2 to be modulated and measured and the affected old waves 1 and 2 are adjusted by the OMS1 and the OMS2, the information needs to be issued to the corresponding nodes (i.e., modulation and measurement sites).

Illustratively, the PCEP PCUpd message may be extended: and packaging the debugging information (or multi-fault information) of the debugging in one message and sending the information to the same destination site. The commissioning information may include, for example, but is not limited to, at least one of the following:

EVOA attenuation, light attenuation adjustment quantity and adjustment points;

And the debugging information of different debugging stations is different. Taking the test station a and the test station B in fig. 6 as an example.

1) Sending a PCEP PCUpd message to the measurement station a, where the measurement information contained in the message may include:

EVOA attenuation, light attenuation adjustment quantity and adjustment points;

the method comprises the steps of (1) measuring the channel number of a wave 1 to be regulated, WSS single wave regulating quantity and regulating points;

the channel number of the wave 2 to be measured, the WSS single wave regulating quantity and the regulating point are regulated;

the number of the affected wave 1 channel, the WSS single wave regulating quantity and the regulating point.

2) Sending a PCEP PCUpd message to the measurement station B, where the measurement information contained in the message may include:

EVOA attenuation, light attenuation adjustment quantity and adjustment points;

the channel number of the affected wave 1, the WSS single-wave regulating quantity and the regulating point;

affected wave 2 channel number, WSS single wave adjustment amount, and adjustment point.

The above is only a simple illustration, and reference may be made to the description of aspect 5 in the method 400 for step 6, which is not described herein again.

And 7, the control equipment receives the testing completion response (for example, recording the testing response) of each OMS section in the current round, and actively inquires the relevant optical power information of the testing service and the affected service.

In a possible case, after receiving the debugging response, the control device actively queries the related optical power information of the debugging service and the affected service, and can re-execute the steps 2-5. And finally, the difference between the service composite wave or single wave optical power of each OMS section and the target optical power is within a certain numerical range, thereby indicating that the service optimization regulation is completed.

Based on the technical scheme, through the control equipment, for example, NETWORK _ OD devices are deployed on the control equipment, and the PCEP protocol is expanded to automatically monitor the optical performance data of the whole NETWORK in real time, the control equipment (or the NETWORK _ OD devices deployed on the control equipment) automatically identifies the batch services with degraded whole NETWORK performance. In addition, the control equipment calculates the target power and the expected effect of the service, calculates the debugging position and the debugging step length (the service to be debugged and the affected service) through the debugging strategy analysis, and centrally controls the parallel debugging of multiple services, multiple OMS sections and multiple debugging stations through the PCEP protocol. Therefore, in the optimized debugging and testing process, the old wave safety is guaranteed, meanwhile, as many parallel debugging and testing as possible are achieved, and the optimized debugging and testing efficiency is improved.

In addition, the control device simultaneously and concurrently issues batch measured values of different network elements (i.e. different measurement stations), and considering that the communication time between the measurement stations is different, it cannot be guaranteed that all the measured values are effective at the same time. Therefore, the control equipment can simultaneously issue the optimal regulating and testing step length of each regulating and testing station and synchronously carry out optical power pre-regulation on the affected service. The aim of safe and rapid regulation is achieved by a mode that all the regulation stations regulate the light power in parallel and approach to the target power step by step, so that the reliability and the safety of parallel regulation and measurement can be ensured.

A specific example is described above in conjunction with fig. 6 and steps 1 to 7. In a centralized control scenario, a NETWORK _ OD device is deployed on a control device, for example, and a PCEP protocol is extended, so as to support automatic parallel optimization debugging. Specifically, a first round of adjustment quantity is issued in parallel through the control equipment, after each debugging station returns a debugging response, real-time optical power information of the service to be debugged and the related affected service is inquired, and a second round of parallel debugging is issued again until one optimized debugging process is completed through multiple rounds of debugging. The parallel optimization debugging mode has more accurate results.

Still taking fig. 6 as an example, another specific example is described below with reference to steps a to F. By deploying a NETWORK _ OD device on the control equipment and expanding a PCEP protocol, the small-step multi-time dispatching and measurement are realized, and a feedback automatic parallel optimization dispatching and measurement mode is performed after certain conditions (such as an accumulated dispatching and measurement threshold) are met.

Step A, automatic real-time monitoring of the optical performance data of the whole network of the control equipment: and acquiring service optical performance data in real time at the single station millisecond level of the equipment.

This step may be referred to step 1 above.

And step B, the control equipment identifies the service to be debugged, which needs to carry out optical power debugging.

This step may be referred to step 2 above.

And step C, the control equipment calculates the target optical power of the service to be regulated and tested.

This step may be referred to as step 3 above.

And D, analyzing and calculating the debugging position and the debugging total amount by the control equipment debugging strategy.

This step may be referred to step 4 above.

And E, the control equipment sends the testing information (which can also be recorded as a testing request) to each testing station.

The control device may schedule the measurements in small steps (e.g., 0.2 db). Because the debugging step length is smaller, the influence of the forward and reverse debugging values on the service is mutually offset, and even if the debugging values are not simultaneously effective due to the communication difference of network elements, the influence on the influenced service is less. After receiving the testing response fed back by each testing station, the control equipment continues to issue the small-step testing information (or testing request), and after multiple rounds of testing, certain conditions are met, and the small-step testing of the current round is finished.

In a possible case, the small-step length debugging of the current round is finished under the condition that the debugging times reach the preset times.

For example, when the number of times of debugging at any debugging station reaches a preset number of times, the current round of small-step debugging may be ended.

For another example, the small-step measurement in the current round may be ended when the total number of times of measurement in all the measurement stations reaches the preset number of times.

In another possible case, the small-step tuning is finished in the current round when the tuning measurement reaches the preset tuning measurement.

For example, when the modulation measurement of any modulation station reaches the first threshold, the current round of small-step modulation is finished.

For another example, the small-step adjustment in the current round may be finished when the total adjustment amount of all the adjustment stations reaches the second threshold value.

Specifically, reference may be made to the description of scheme 2 in the method 400, which is not described herein again.

And F, the control equipment inquires the optical power information of the debugging service and the affected service.

It can be understood that, after a certain condition is satisfied, the control device queries the optical power information of the modulation service and the affected service.

In a possible case, after receiving the modulation response, the control device actively queries the modulation service and the optical power information related to the affected service, and may re-execute steps B to E. And finally, the difference between the service composite wave or single wave optical power of each OMS section and the target optical power is within a certain numerical range, thereby indicating that the service optimization regulation is completed.

Still another specific example is described above in connection with fig. 6 and steps a to F. In a centralized control scene, through control equipment, for example, NETWORK _ OD devices are deployed on the control equipment, and a PCEP protocol is expanded, so that multiple times of debugging and measurement with small step length are realized, and an automatic parallel optimization debugging and measurement mode for feedback is performed when a certain condition (for example, after a measurement threshold is adjusted accumulatively) is met. Specifically, the automatic parallel optimization debugging and measuring mode that small-step-length multiple-time issuing of each debugging and measuring station is used can be considered, feedback is carried out when certain conditions (such as after a certain debugging and measuring is accumulated), time consumed by multiple-time network real-time optical power query is reduced, meanwhile, each debugging and measuring point is issued according to a small step length, the debugging and measuring value issued for the second time in a small step length carries the regulating quantity of the affected service, and the safety of the old wave service is guaranteed. The method is more suitable for the scene that the network topology is large and the span of the service to be regulated and the affected service passing through the network element is large.

It should be understood that the names of the messages referred to in the above embodiments do not limit the scope of the embodiments of the present application. For example, in the future protocol, a name for indicating a function similar to that of the control device is also applicable to the embodiment of the present application.

Based on the technical scheme, an automatic parallel optimization debugging and testing method is provided. The control equipment debugging center monitors the service light performance data in real time, automatically identifies the service to be debugged based on the analysis of the service light performance data, calculates the debugging target power and effect, determines a parallel debugging strategy, centrally controls each debugging point and executes parallel debugging. Therefore, the demand of the customer for fast and automatically optimizing and debugging can be met.

In addition, parallel debugging and testing can be implemented through small-step issuing. Under the condition of ensuring safety, the parallel debugging and testing of the services are realized to the maximum extent, and the efficiency is improved. But also to a plurality of survey scenarios, which may include, for example but not limited to: open bureau debugging, capacity expansion debugging, heavy route debugging and the like.

Furthermore, the parallel debugging scheme provided by the application can improve debugging efficiency and ensure debugging safety.

On the one hand, the debugging efficiency can be improved. And the debugging stations perform parallel debugging and testing, the upstream and downstream adjustment quantity hedging is considered, independent truncation operation is not needed, the main optical path and the single-wave step length are independently calculated and decoupled with each other, the repeated calculation of the combined-wave power adjustment quantity is avoided, and the debugging times are reduced.

On the other hand, the regulation and measurement safety can be ensured. For example, the small step size debugging considers the single OMS step size constraint and the OCH level equidirectional debugging step size constraint. And considering the asynchronous network element communication, limiting the same-direction step length constraint, thereby ensuring the same-direction effect. And for another example, the adjustment and measurement are carried out for multiple times in small step length, and feedback is carried out after a certain condition is met (for example, after the accumulated adjustment and measurement reaches a certain threshold). And the phenomenon that the performance fluctuation is too large due to the fact that the adjustment amount is too large during single issuing is avoided. Furthermore, the hedging ensures: namely, the parallel regulation and measurement realizes the small step hedging of the upstream and downstream power, and avoids fluctuation.
